Air-conditioning vent vane adjusting device

ABSTRACT

An air-conditioning vent vane adjusting device includes a driving board for driving a vane to rotate, a push-button installed on the wind gate panel, and a connecting element of the driving board. The connecting element includes a fixed plate coupled to the push-button and moved together with the push-button, and the fixed plate has a guide notchnotch tilted with respect to the lengthwise direction of the driving board. The driving board has a lug accommodated in the guide notchnotch and capable of sliding in the guide notchnotch. With the tilted guide grove and the lug, the driving board can be moved reciprocally to overcome the problems of requiring a large operating force of the push-button of the tight assembly of the conventional driving board and connecting element and the difficulty of opening and closing a vane.

BACKGROUND OF THE INVENTION

1. Field of Invention The present invention relates to a component of a central air-conditioning system, and particularly to an air-conditioning vent vane adjusting device.

2. Description of Related Art

As people's standard of living standard improves, central air-conditioning is used extensively. Outdoor air-conditioning units are installed outdoors according to the required area of use, and air-conditioning terminals are installed in indoor rooms, such that air heated or cooled by the outdoor air-conditioning units can be transmitted into an air-conditioning vent of each room through a connecting pipeline and then passed out of the air-conditioning vent, so as to regulate the temperature, humidity and freshness of the air in the rooms to meet user requirements for comfort. In general, a conventional air-conditioning vent comprises a wind gate panel installed on a wall and disposed at a frame on an inner side of the wind gate panel, and a plurality of vanes rotatably mounted on two opposite sides of the frame, and the vanes have an end passing through the frame to connect a driving board, and the driving board is connected to a push-button on the wind gate panel by a connecting element, so that the push-button can slide on the wind gate panel to drive the driving board to move reciprocally in order to open or close the vanes, and open or close the vent, and the control push-button can be moved to control the rotation angle of the vanes in order to adjust the wind flow as disclosed in PRC Pat. No. CN201246856Y, entitled “A vane adjusting mechanism for wind gates”.

SUMMARY OF THE INVENTION

In view of the aforementioned drawbacks of the prior art, it is a primary objective of the present invention to overcome the aforementioned drawbacks of the prior art by providing an air-conditioning vent vane adjusting device with the features of a labor-saving adjustment, a convenient installation, and a low cost.

To achieve the foregoing objectives, the present invention adopts the following technical measure and provides an air-conditioning vent vane adjusting device, comprising: a driving board for driving a vane to rotate, a push-button installed on a wind gate panel, and a connecting element of the driving board, characterized in that the connecting element comprises a fixed plate coupled to the push-button and capable of moving with the push-button, and the fixed plate includes a guide notch formed thereon and tilted with respect to a lengthwise direction of the driving board; and the driving board has a lug accommodated in the guide notch and capable of sliding in the guide notch.

To take the convenience and easiness of manufacture and installation as well as the simplification of the structure into consideration, a connecting plate can be fixed onto the driving board, and the lug is disposed on the connecting plate.

Preferably, the included angle between the lengthwise directions of the guide notch and the driving board falls within a range of 40-50 degrees. The smaller angle of the pushing force, the better the hand feel.

In the aforementioned solution, the guide notch can be replaced by a groove. However, the opening structure can provide an easy installation. Specifically, the opening of the guide notch can be defined at the lower edge of the fixed plate.

Compared with the prior art, the present invention using the tilted guide notch and the lug together to drive the driving board to move reciprocally, so as to overcome the problem of the prior art that requires a large operating force of the push-button caused by the tight assembly of the conventional driving board and has the difficulty of opening and closing the vanes, so that the operation of the push-button has the features of moderate operating force, power saving, and good hand feel, and the present invention has the advantages of a simple structure, a convenient installation, and a low cost to better meet the current market requirements of the air-conditioning vent.

DETAILED DESCRIPTION OF THE INVENTION

The technical characteristics and objectives of the present invention can be further understood by the following detailed description of preferred embodiments and related drawings.

With reference to FIGS. 1 to 5 for the structure of an air-conditioning vent used by an air-conditioning vent vane adjusting device in accordance with a preferred embodiment of the present invention, the air-conditioning vent comprises:

-   -   a wind gate panel 1, including a grating 11, and a slide 12         disposed on the wind gate panel 1;     -   a frame 2, installed on a wall, and disposed on an inner side of         the wind gate panel 1, and provided as a connecting base for         connecting components such as the wind gate panel 1, vanes, and         a driving board, wherein the frame comes with a large frame         structure;     -   a plurality of vanes 3, with both ends rotatably mounted onto         two opposite sides of the frame, and each vane having a         connecting shaft 31 disposed on the same end of the vanes; and     -   a driving board 4, corresponsive to the connecting shaft 31 for         fixing and coupling the connecting shaft 31 thereon.

In FIGS. 1 to 5, the air-conditioning vent vane adjusting device of this preferred embodiment further comprises:

-   -   a push-button 5, installed on the wind gate panel 1, and having         a lower portion passing through a slide formed on the wind gate         panel 1 and disposed on an inner side of the wind gate panel,         and the push-button 5 being capable of sliding in a lengthwise         direction along the slide on the wind gate panel;     -   a fixed plate 6, installed parallel to a side of the frame and         disposed on an inner side of the wind gate panel, and coupled to         the bottom of the push-button 5, such that the fixed plate 6 can         be moved reciprocally by the sliding of the push-button, wherein         the fixed plate includes a guide notch 61 tilted with respect to         the lengthwise direction of the driving board, and an included         angle of 45 degrees is defined between the lengthwise directions         of the guide notch 61 and the driving board of this preferred         embodiment, and the guide notch 61 is defined at a lower edge of         the fixed plate; and     -   a connecting plate 7, fixed and coupled to the driving board 4,         and having a lug 71 disposed on the connecting plate 7 and         accommodated in the guide notch 61, and capable of sliding in         the guide notch 61 along the lengthwise direction of the guide         notch 61.

The air-conditioning vent vane adjusting device is operated according to the following principle:

To open the vanes for ventilation, the push-button is pushed on the wind gate panel, so that the push-button slides in the slide to drive the fixed plate connected to the push-button to move together. The lug slides in the guide notch, so that the connecting plate drives the driving board to move. The driving board pushes the connecting shaft on the vane, so that both ends of the vane rotate in the mounting hole of the frame to open the vane as shown in FIG. 4.

To close the vanes, the push-button is operated reversely.

To adjust the size of the opening of the vane, the push-button is pushed to a corresponding position.
